Saturated and Anisotropic Magnetostriction in an Altermagnet
Zhiyuan Duan, Qiyun Xu, Peixin Qin +14
Magnetostriction, a fundamental phenomenon bridging magnetism and mechanics, has enabled a broad spectrum of applications. For almost two centuries, it has been mainly investigated…
Giant Room-Temperature Third-Order Electrical Transport in a Thin-Film Altermagnet Candidate
Hongyu Chen, Peixin Qin, Ziang Meng +14
Quantum geometry, a quantum mechanical quantity comprised of Berry curvature and quantum metric, describes the geometric structure of the electronic bands in solids. The correlatio…
Bulk OsO2 Single Crystals: Superior Catalysts for Water Oxidation
Guojian Zhao, Zhihao Li, Ziang Meng +13
Although rutile RuO2 has been a well-known and almost the best oxygen evolution reaction (OER) catalyst, the OER properties for the similar rutile oxide OsO2 with the same group el…
Pressure-Induced Metal-Insulator and Paramagnet-Altermagnet Transitions in Rutile OsO2 Single Crystals
Guojian Zhao, Ziang Meng, Wencheng Huang +19
Altermagnets with compensated spin structures and nonrelativistic spin splitting have emerged as a new class of magnetic materials. Rutile OsO2 has been theoretically predicted to…
Observation of Orbit-Orbit Torques: Highly Efficient Torques on Orbital Moments Induced by Orbital Currents
Hongyu Chen, Han Yan, Xiaorong Zhou +10
We study the current-induced torques in bilayers composed of a light 3d metal, chromium, and a rare-earth ferromagnet with finite orbital moments, terbium, utilizing second-harmoni…
Electric-Field-Controlled Altermagnetic Transition for Neuromorphic Computing
Zhiyuan Duan, Peixin Qin, Chengyan Zhong +12
Altermagnets represent a novel magnetic phase with transformative potential for ultrafast spintronics, yet efficient control of their magnetic states remains challenging. We demons…
